Atrial cellular electrophysiological changes in patients with ventricular dysfunction may predispose to AF [PDF]

, 2009
<b>Background:</b> Left ventricular systolic dysfunction (LVSD) is a risk factor for atrial fibrillation (AF), but the atrial cellular electrophysiological mechanisms in humans are unclear.

Left ventricular function in acute inflammatory peri-myocardial diseases – new insights and long-term follow-up

Cardiovascular Ultrasound, 2012
Background Until recently acute inflammatory peri-myocardial syndromes have been associated with global rather regional left ventricular (LV) dysfunction. Recent advances in cardiac imaging with echocardiographic techniques and magnetic resonance imaging

Microfabricated Anisotropic Myobundles for the Scalable Production of Cardiac Tissue Grafts

Advanced Functional Materials, EarlyView.
Controlling the anisotropy of cardiac tissue remains an outstanding challenge in the field of cardiac tissue engineering. Here, we introduce an approach to generate anisotropic cardiac myobundles using cell‐adhesive, synthetic, electrospun fibers and stem cell‐derived cardiac fibroblasts.

Mechanical and Electrical Phenotype of hiPSC‐Cardiomyocytes on Fibronectin‐Based Hydrogels

Advanced Healthcare Materials, EarlyView.
We introduce fibronectin‐based PEG hydrogels with controlled rigidity to enable the culture of iPSC‐derived cardiomyocytes. These substrates offer an alternative to the current culture of these cells on fibronectin‐coated glass, providing enhanced structural and functional behavior. The system provides a more physiologically relevant platform to assess

Left atrial reservoir strain as a predictor for left ventricular filling pressure in patients with sinus rhythm

Scientific Reports
We aimed to evaluate the utility of left atrial reservoir strain (LASr) as a predictor of left ventricular (LV) filling pressure measured via catheterization in patients with sinus rhythm.

Translational Considerations for Injectable Biomaterials and Bioscaffolds to Repair and Regenerate Brain Tissue

Advanced Healthcare Materials, EarlyView.
The repair and regeneration of brain tissue faces both biological and technical challenges. Injectable bioscaffolds offer new opportunities to stimulate tissue regrowth in the brain by recruiting neural stem cells. Here, the translational issues are reviewed that need to be address to advance this promising new therapeutic approach from the bench to ...

The brain in heart failure [PDF]

, 2004
After atrial fibrillation, heart failure is the second most frequent cardiac association of stroke. Deteriorating left ventricular systolic function appears to increase the risk of cardioembolic stroke in heart failure.

Infusible Extracellular Matrix Biomaterial Enhances Cell‐Specific Pro‐Repair Responses Following Acute Myocardial Infarction

Advanced Healthcare Materials, EarlyView.
We measure the cell‐specific responses of administering infusible ECM (iECM) in acute myocardial infarction (MI) across multiple timepoints. Using single‐nucleus RNA sequencing and spatial transcriptomics, we measure macrophage activation, fibroblast remodeling, increased vascular development, lymphangiogenesis, cardioprotection, and neurogenesis ...
